This dataset is part of the Microfinish Comparator series. A comparator can be used to qualitatively gage surface finish, by comparing it to a sample visually or by touch. This is the 4L lapped sample. The GAR S-22 microfinish comparator gage used for this series. Measured via Zygo ZeGage Plus (10x) Data source: Digital Metrology … Read more

This dataset is the focus of our blog post, How to Remove Shape from a Complex Surface. In the post we show how to use the tools in OmniSurf3D to tame a difficult surface and accurately measure features despite the complicated, underlying surface. Measured via GelSight Mobile. Data source: Asist. Prof. Alp Eren Şahin and … Read more
A quality cast iron pan is a great cooking surface that can last for generations. This dataset shows the surface of a new Lodge cast iron pan, which is shown under the Zygo ZeGage microscope, below. The cast iron is a fairly coarse surface. Looking at statistics for the dataset we can see that the … Read more
Is a non-stick pan surface slippery because it’s smooth? This dataset shows the surface of a Ninja Foodi Never-Stick pan. The surface is extremely durable, even against metal utensils, but will not stick. So, is it slippery because it’s smooth? Not even close! The Sq value is over 6 µm, which is on par with … Read more
How can you tell where a crack will form? It’s particularly difficult for a surface such as this one, with complex texture consisting of machining marks from various operations. Perhaps we would look for the deepest scratches (the blue areas in the image above) to predict where cracking may occur. However, cracks tend to form … Read more
